1. A method for path selection proportional to a penalty delay in processing packets, the method comprising: identifying, by a first device intermediary to a plurality of a clients and one or more servers, a delay penalty for processing one or more packets of a server of the one or more servers destined for a client of the plurality of clients, the first device in communication via a plurality of links of different latencies with a second device intermediary to the one or more clients and the first device; selecting, by the first device, from the plurality of links other than a first link of the plurality of links with a lowest latency, a second link with a latency that deviates from the lowest latency of the first link by at least the delay penalty; transmitting, by the first device to the second device, duplicates of the one or more packets to the second device via the selected second link with information indicating to the second device to hold the duplicates of one or more packets at the second device; receiving, by the first device, an indication to one of drop or send the duplicates of the one or more packets to the client; and transmitting, by the first device, the indication to the second device to one of drop or send the duplicates of the one or more packets according to the indication.
This invention relates to network packet routing and addresses the problem of optimizing path selection in data transmission to minimize processing delays. The method involves a first intermediary device positioned between multiple clients and servers, which identifies a delay penalty associated with processing packets from a server destined for a specific client. The first device communicates with a second intermediary device via multiple links of varying latencies. Instead of using the lowest-latency link, the first device selects a different link whose latency deviates from the lowest-latency link by at least the identified delay penalty. The first device then transmits duplicate packets to the second device via the selected link, including instructions for the second device to hold the duplicates. The first device subsequently receives an indication to either drop or send the duplicates to the client and transmits this instruction to the second device. This approach ensures that packet delivery is adjusted based on processing delays, improving overall network efficiency by dynamically selecting alternative paths to balance latency and reliability. The method avoids overloading the fastest link while maintaining data integrity and minimizing unnecessary retransmissions.
2. The method of claim 1 , further comprising transmitting, by the second device, the duplicates of the one or more packets to the client instead of the one or more packets responsive to the indication from the first device indicating to send the duplicates of the one or more packets.
This invention relates to network communication systems, specifically methods for improving data transmission reliability between devices. The problem addressed is ensuring data integrity and reducing packet loss in communication networks, particularly in scenarios where packet duplication can enhance reliability. The method involves a system with at least two devices and a client. The first device monitors network conditions and determines when packet duplication is necessary to prevent data loss. When such conditions are detected, the first device sends an indication to the second device. Upon receiving this indication, the second device generates duplicates of one or more packets instead of transmitting the original packets. These duplicates are then sent to the client, replacing the original packets. This approach ensures that the client receives multiple copies of critical data, increasing the likelihood of successful transmission even if some packets are lost or corrupted. The method is particularly useful in environments with high packet loss rates or unreliable network conditions, such as wireless networks or congested data paths. By dynamically adjusting packet transmission based on real-time network conditions, the system improves data delivery reliability without requiring additional bandwidth for all transmissions.
3. The method of claim 1 , further comprising dropping, by the second device, the duplicates of the one or more packets so that the client does not receive either the one or more packets or the duplicates of the one or more packets.
This invention relates to network communication systems, specifically addressing the problem of duplicate packet transmission in data networks. In such systems, packets may be duplicated during transmission, leading to redundant data being sent to a client device. This redundancy wastes bandwidth and processing resources, potentially causing inefficiencies in network performance. The invention describes a method for handling duplicate packets in a network where a first device transmits one or more packets to a second device, which then forwards them to a client. The second device detects duplicates of the transmitted packets and actively drops them before they reach the client. This ensures that the client receives only the original packets, eliminating redundant data and improving network efficiency. The method involves identifying duplicate packets based on their content or metadata, such as sequence numbers or timestamps, and discarding them to prevent unnecessary transmission. By dropping duplicates at the second device, the system avoids overloading the client with redundant data, reducing bandwidth consumption and processing overhead. This approach is particularly useful in networks where packet duplication is common, such as in wireless or unreliable transmission environments. The method enhances data transmission reliability and efficiency by ensuring that only unique packets are delivered to the client.

The third device stores or forwards the duplicates to ensure data integrity and reliability. This redundancy mechanism helps recover lost or corrupted packets, improving communication robustness in unreliable networks. The method may include error detection, retransmission protocols, or synchronization between devices to maintain data consistency. The system can be applied in wireless networks, distributed computing, or any scenario where packet loss mitigation is critical. The invention ensures reliable data delivery by leveraging multiple transmission paths and redundant storage, reducing the risk of data loss and enhancing overall system performance.
